How do we know God's promise of a Savior is true?

The promise of a Savior is first recorded in Genesis 3:15, where God declares, 'I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his heel.' This proclamation not only reveals God's immediate response to sin but also sets in motion the entire narrative of salvation history. Throughout the Old Testament, various prophecies reinforce the coming of the Messiah, culminating in the New Testament with the arrival of Jesus Christ, who fulfills these promises. The apostle Paul encapsulates this truth in Galatians 4:4-5, stating that God sent His Son 'when the fullness of time had come, born of woman, born under the law, to redeem those who were under the law.' This demonstrates the certainty of God's promises and His faithfulness across generations.
